OIL-BURNING APPARATUS.

A Application filed June 16, 1923. Seriallt'o. 645,845.

To all whom it may 1, PETER E.

new and useful Improvements in Oil-Burn ing Apparatus, of which the specification. H

My invention relates, generally, to oil burning apparatus adapted for installation in connection witlfdomestic and industrial furnaces, and more particularly to means for automatically cutting ed the flow of oil in the event that the supply of air which is combined with said oil to form combustible mixture should be interrupted from any cause, thereby avoiding the danger arising from overflow of the oil. In order that the invention'may be fully understood, reference will now be had to the accompanying drawings, in which:

Fig. 1 is a side elevation of-the apparatus following is a partly in section.

2 is an enlarged broken vertical secg fthe tionj showing the important features invention.

Fig. 3 is an irregular vertical cross section on line HIIII of Fig. 1.

Fig. 4 is a broken irregular lbngitudina1 section on line IV-IV of Fig. 2.

Fig. 5 is a broken side elevation, partly in section, of a modified form of the invention.

Fig. 6 is a broken rear elevation of the modified form.

Referring now in parts disclosed by Fi designates an air pipe intake end to a housing site end to a nozzle 6, retort 8, or any other suitable burner for a combustible mixture of air and fuel oil.

10 designates any suitable air current creating mechanism, shown in the present instance in the form of a blower connecte to the housing 4 and having an air intake opening 12 and a discharge opening 14, which latter is, preferably, in axial alinement with the air pipe 2 as more clearly disclosed by Fig. 2.

16 designates a vane or any other member adapted to be actuated b current'created by the blower 10. aid vane 16 is fixedly connected to a rock shaft 18 from which it is suspended in such manner as to normally close the discharge opening detail to the various "s. 1 to 4, inclusive,

connected at its 4, and at its oppodischarging into a suitable -connected to an oil feed pipc a highly.

.di scharged through the pipe 30 the air 14. The rock shaft 18 is journaled in opposite sides of the housing 4'and provided with a fixedly-mounted eccentric 20 upon which a counterweight 22 rests. The counterweight 22 is mounted upon one end of a lever 24 fulcrumed at its opposite end upon a bracket 26 clamped upon a suitable support such as a manually-controlled valve 28 from a suitable source of supply, not shown, and connected to an oil jet 32 extending centrally through the nozzle 6 and adapted to discharge into the retort 8. The lever 24 has a pin-andlot connection 34 with a valve 36; which is rendered self-closing through the intermediacy of counterweight 22. Said valve 36 is connected to the oil pipeadjacent to the valve 28, which has a hand wheel 38 whereby it may be opened and closed. I

40 designates a motor, preferably of the electric type, mounted upon a base 42 and provided with a mounted.

In practice the manually-controlled valve 28 is opened sufficiently to permit the desired quantity of oil to fiow through the pipe 30 to the oil jet 32 from which it is into the retort 8. The motor...'40 is also started to drive the blower which forces a current of air through the pipe 2 30 leading I drive shaft 44 upon which: the rotor 46 of the blower 10 is fixedly Oil to the air nozzle 6 from which it discharges with suflicient velocity to convert the oil discharged from the oil jet 32 into spray, the air becoming thoroughly mixed with 2 said spray and forming a highly combustibl'e m1xture which suitable means.

The current of air created by 10 swings the vane 16 upwardly to the dotted position disclosed by Fig. 2, causing said vane 16 to rock the shaft 18, which in turn rocks the eccentric 20, so that the hi h radius thereof will engage the counterweig t 22 and raise the same and the lever 24 to may be ignited by any the dotted lineposition, thereby opening the valve 36 and allowing the oil to flow to theoil jet 32, as Should the motor 40 stop from any cause and thus fail to actuate the blower 10 the vane 16 immediately moves downwardly by, the force of ravity to the full line position disclosed y Fig. 2,

above stated.

the blower causing the high radius of the eccentric 20 to pass out of engagement with the counterdischarge opening.

weight 22 and thereby permitting the same and the lever 24 to automatically close the valve 36 and shut off the flow of oil to the jet 32. By thus automatically cutting off the flow of oil when there is no air current to form a highl combustible mixture the danger arising rom an overflow of oil is obviated. Y

In the formjdisclosed by Figs. and 6 the principle is, the same as that disclosed by Figs. 1 to 4, inclusive, as evidenced by corresponding reference numerals with exponents a, the chief difference being that the vane 16 is arranged at the intake opening 12 of the blower -10 When the blower 10 is at rest the vane 16 normally stands in open position as disclosed by Fig. 6', but is drawn inwardly against the intake 12 by the current of air created by the blower when the same is in operation. The vane 16 is fixed to a shaft 50 mounted in bearings 52 and provided with a fixedly mounted crank 54,.

' connected to another crank 56 through the intermediacy of a connecting rod 58. The crank 56 is fixed upon the rock shaft 18 carrying the eccentric 2O upon which the counterweight 22 rests; When the blower 10 is in operation the air current created thereby carries 'the vane 16 across the intake 12, causing said vane 16, through the intermediacyof the intervening mechanism, to open the valve 36 and permit oil to flow to the retort through the oil pipe When the blower .10 is at ried by the force of gravity away fromthe instead of at the rest the vane 16 is carintake 12* and permits the counterweight 22 and the lever 24 to close the valve 36*. The vane 16 has a plurality of openings 60 through which the air current passes when the blower is in operation, and draws said vane 16 across the intake 12.

While it is. preferable to place thevane either adjacent to the intakeaor discharge opening of the blower, owing to the fact that the air current is stron est at these points, it is'to be understoodt at the vane, or its equivalent, may be located at any suitable point where it will be acted upon by the air current and effect the opening of the self-closing valve.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

In combination with a burner, an oil pipe for supplying said burner with fuel oil, an air pipe for supplying said burner with air, a "ane controlled said air pipe, a

rock shaft on which said vane is fixedly mounted, an eccentric fixedly I mounted on said rock shaft, a valve for controlling the flow of oil through the oil pipe, a lever for openin and closing said valve, and a counterweigit fixed to said lever to actuate the same and resting on said eccentric in order to be actuated thereby.

In testimony whereof I aflix my signature, in the presence. of two witnesses.
